Abstract:Manual welding operations remain totally dependent on the instincts of the operator and the operator's ability to collect information through normal sight and sound. The proposed innovation will apply modern data presentation technology to enhance the welder's perception of the welding situation.… more
Abstract:The focus of the Phase I work proposed herein is the preliminary design of a Coherent Phase Cavitation Monitoring System (CPCMS) for turbomachinery. Cavitation is the process of boiling water which occurs when local hydrodynamic pressures in the areas of accelerated flow drop below the vapor… more
Abstract:Hybrid rocket propulsion systems are attractive because they use a single fluid (LOX), and avoid the high injector part count of dual fluid propulsion systems. However, the hole drilling costs associated with fabricating the injectors can be large, and the small holes that are desirable to achieve… more
Abstract:The proposed effort covers the engineering aspects of a magnetic field source to be used in a table-top demonstrator of magnetic refrigeration. A prototype magnetic field source, based on the Halbach or "magic-ring" concept, will be designed, constructed and tested in the Phase I effort. The… more
Abstract:Stability of the optical properties of materials in the space environment is a limiting technology in the development and operation of spacecraft. The complex space environment can damage exposed materials including thermal control surfaces. The thermal radiative properties of these materials are… more
Abstract:We propose to develop an innovative class of electrically conductive thermal control coatings (both white and black). This will be accomplished through the use of current state-of-the-art organo-metallic, sol-gel techniques and the use of state-of-the-art solid state physics, chemical sciences and… more
Abstract:With the present compelling need for treatment of narcotic addiction, there is the requirementfor a controlled release device that would ensure compliance with a narcotic antagonist regimen, butwhich could be removable should the patient's circumstance require it. Promising in this regard… more
Abstract:Recent CFDRC studies have demonstrated the advantages of developing back to back radial/mixed flow monorotor technology fully integratable between an ATR tailored solid fuel gas generator (SFGG) and a high heat release combustion chamber. To achieve an ATR Isp over 1500 seconds, the turbine half… more
Abstract:In the field of Computational Fluid Dynamics (CFD), a multi-zonalapproach greatly facilitates adequate representation of complexgeometry and different flow physics in different parts of theflow domain. Previous multi-zonal patched and overlappedappro
Abstract:Innovative unstructured, density-based CFD methodology will be developed in this project applicable to low-speed, turbulent reacting flows. In Phase I, the feasibility of using finite rate kinetics in an unstructured CFD environment will be addressed. An existing unstructured, density-based,… more
Abstract:Preliminary CFDRC assessment indicates the proposed low cost solid fueled Air- Turbo-Rocket (ATR) can exceed current Navy requirements for an affordable supersonic expendable aerial target propulsion system. Existing vehicle/propulsion/trajectory software and system/component design experience will… more
Abstract:The proposed electrostatic atomization process has been successfully applied within the diesel injection and paint spray industries to generate a priori specifiable droplet-size distributions with near uniform droplet dispersivity. Energetically efficient droplet development with electronically… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
